操作系统：deepin linux 2013 或 ubuntu 13.04
1、安装交叉编译前。须要安装的包
sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt xsltproc
2、下载OpenWrt的源码
git clone git://git.openwrt.org/openwrt.git cd openwrt ./scripts/feeds update -a ./scripts/feeds install -a make defconfig make prereq make menuconfig
依照下图选择相应的项目
3.关键的一步
cd package mkdir node sudo gedit Makefile

define Package/node/description
Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

4.保存配置文件后编译： make V=99 （參数为输出调试信息）
5.把openwrt/bin/ramips/packages下的
node_v0.10.28-2_ramips_24kec.ipk
uclibcxx_0.2.4-1_ramips_24kec.ipk
复制到路由器，先安装uclibcxx_0.2.4-1_ramips_24kec.ipk库，再安装node_v0.10.28-2_ramips_24kec.ipk，安装node的时候要耐心等待，我第一次安装的时候等了一会没有响应。以为编译失败了，终止了安装进程。因此而耗费了非常多时间。
后记：
看到恩山WIFI论坛网友soonco的帖子把编译过程中可能遇到的问题说得非常明确，当时我也走过类似的弯路。便摘录下来作为补充
http://www.right.com.cn/forum/thread-141085-1-1.html
HG255D的CPU是Ralink RT3052。mipsel的make
要是启用ssl功能就把“–without-ssl”删掉
假设是ar71xx的u请把里面的mipsel替换成mips
假设是arm的cpu请把替换
LIBS:=-I$(TOOLCHAIN_DIR)/arm-openwrt-linux/include/c++/{gcc版本}/ -I$(TOOLCHAIN_DIR)/arm-openwrt-linux/include/c++/{gcc版本}/arm-openwrt-linux-uclibcgnueabi/
和
./configure –dest-cpu=arm –dest-os=linux –without-ssl –without-snapshot –with-arm-float-abi=soft;
以此类推
无论什么版本号的openwrt版本号里面的node make文件都是出自 https://github.com/giorrrgio/nodejs-linino
（实际上我文章中提到的make文件是出自https://github.com/brimstone/nodejs-openwrt，可是也有參考过nodejs-linino）
mips的建议用attitude adjustment分支编译，不然总出错
mipsel直接用trunk就成了
特别注意：attitude adjustment的gcc版本号是4.6.3，而trunk的gcc是4.8.3
